Why Flutter + Rails?
Flutter and Ruby on Rails are a powerful combination: Flutter delivers beautiful, native-performance mobile apps for iOS and Android from a single codebase, while Rails provides a robust API backend. Together, they offer the fastest path to a production-quality full-stack mobile application.
Architecture Overview
Flutter app communicates with Rails API via JSON over HTTPS. PostgreSQL stores the data. Background jobs handle async processing.
JWT Authentication Flow
Rails generates JWT tokens on login, Flutter stores them securely with flutter_secure_storage, and attaches them to every API request.
State Management with Riverpod
We recommend Riverpod for state management — it's type-safe, testable, and integrates cleanly with API calls using FutureProvider and StreamProvider.
Real-Time Updates
Use Action Cable with the action_cable Flutter package for real-time features like chat and notifications.
